Where are people buyng these OEM rsx base axles? I'm looking to replace my axles (k24 eg), and my go to OEM parts sites (acuraoemparts, oemacuraparts, hondapartsunlimited) both list the axles at $500+ EACH? Have the prices skyrocketed, or am I just looking in the wrong place?

IE: In all these references to OEM rsx base axles as affordable alternatives (that some tout as being higher quality then) to the aftermarket options out there (I'm thinking DSS Level 0, or Hasport. A quality axle designed for bolt on street cars) are people referring to true OEM parts directly from honda? Which are listed at over $500 each on all the major oem parts websites, that doesn't seem to fit into the affordable alternative description noted above. Or are we referring to autozone aftermarket OEM replacements? (I'd guess $50-$70 each)

We're talking about used OEM axles. Try car-part.com. You can find used OEM axles ranging between $25-75. For overall best reliability (and never a worry about axle issues again), try our 36mm Swap Hubs, which allow you to run the larger diameter OEM Honda/Acura axles.

You are actually the 2nd person to recommend used axles and car-part. I always thought of axles as a wear part that you would want to avoid buying used? Would an OEM axle with unknown mileage (I'd guess most base rsx's out there are well into 6 digits) really be a better option then something like the DSS level 0? or even cheap autozone stuff. The DSS level 0's are $300 for the pair, so I'd imagine $150 each.

Edit: I also imagine it would be difficult to buy a driverside axle and find a passenger side inner to swap it with. I only need to replace the driver side at the moment (not sure if i mentioned that).

Or am I mistaken and buyng used axles is common and effective (what most people who run the common base rsx axle set up do?

used OEM base axles fo'sho.
You can buy rebuild kits from Honda/Acura if you're nervous about running used axles as they are from the seller.

swapping the inners is no big deal if you have both of the axles, you can do it yourself.

If you just need a driver side, find an 02-04 EP3 axle set and use the driver side. straight plug n play and the length is perfectly fine for auto-x/road race use (i'm rocking one myself). EP passenger side is another story (too short), but is useful for the inner and outer joints as spare parts.

Just getting an ep3 driverside axle sounds like my best bet so I don't have to buy 2 axles right now, all the vibration seems to be coming from the driver side axle. I'm looking for an oem rebuild kit and not finding it, have a part number?

Not sure what you're wanting to repair/rebuild, tho I'd assume just the boots & grease.

There's a couple rebuild kits Acura offers.

1) boot/grease/clamp kit (for inners and outers)
2) inner joint kits (cup with new tripod, 3 bearings, a couple circlips)
3) outer joint kits (whole assembly...spline/cup, ball/cage all put together).

Look for 'joint set' and 'boot sets' which are the kits...The joint sets can get pricey! Look here:

would be nice if Acura sold the damb inner tripod bearings ala carte. Getting those wpc treated would be tiiiiiiite btw.

Re: RXS base axles works for EG!!!

Advice on what will I need
US spec DC2-R 5lug (32mm)? or JDM 5lug (36mm)?

if JDM, go k20a2 axles.
It's suggested to swap inners but others have ran A2 axles unswapped without issues. Your vehicle height matters tho, too low (tucking) = swapping inners is highly suggested.

Karcepts has some axle details here:
http://www.karcepts.com/shop/product.php?id_product=53

EDIT/UPDATE - I had some recent discoveries of my own (which Karcepts site already mentions), but just confirming that a K20Z3 passenger side axle is the perfect axle for 36mm 5-lug swappers on EG, EK (w/ekk2 mounts), and DC2 chassis's. These are for people who are experiencing that using both RSX-S axles (unswapped) may seems too short and is stretching the inner boot a little too much for comfort and/or who are experiencing passenger side axle failure. Z3 pass.side axle is the golden length! A2 driver side is perfectly fine to use from the 3 fellas I've been dealing with lately. I find this phenomenom with the 36mm 5 lug conversion highly irritating because one of the 3 fellas I was helping is using OEM A2 axles (unswapped) in his DC2 and doesn't have inner boot stretch issues and has tracked his car a few times without issues, while the other 2 fellas kept having passenger side axle failure after a certain period of time, yet when they switched to a Z3 axle its like heavens gates open up for them and no more issues.

Wow I just read 496 posts!!!! I'm a newbie but I have gathered some information from reading this ENTIRE post off and on for three days:
1-most of you didn't even bother reading the entire post ...from post 1, and you can tell by the repetitive questions being asked.
2-a lot of the posts are off-topic and just shouldn't be in a post about eg k swap rsx base inners being swapped.
3-Karcepts is willing and able to do the real leg work. And he stuck with this post and repeated himself way longer and more than I would have. He has very good patients.
4-ep3 axles WONT WORK ... They are too short!!!
5-rsx base oem axles work ok with inners swapped on eg with k swap.
6-gsp axles will work if you can swap the inners. Some axles have different tripods/bearings and won't allow you to straight swap without swapping the tripods. Some won't work at all because the actual shafts are different sizes. And some can literally be pulled out of one side and stuck in the other.
7-the answer I needed was in the very first post.
8-always read an entire post thoroughly before commenting

I want to know how those swamped inners are holding up on the eg's with base rsx axles? Karcepts is there any new information? I'm on innovative mounts with 75a inserts. Base Japanese k20a w/ 5 speed. Using "32mm" 4 lug oem. If not I'm just going to go to the store and start measuring axles. I'll post my findings.

Correction - USDM EP3 driver side axle is totally fine to use in a 4x100 scenario. I'm using one myself. Its the EP3 passenger side that is too short and shouldn't be used, or only to be used for donor parts for its inner & outer joints & tripod bearings. The pass.side shaft itself is too short for K-swap use.

Just get OEM base rsx axles and swap the inners for peace of mind. You'll be fine with those and they'll hold up. Swapping the inners around doesn't hamper reliability at all as long as they're genuine OEM honda axles. China made shit I'm not so sure about.

Haha... Well, I don't have any patients, but I am about out of patience on this thread... =p

We've moved on from RSX Base swapped axles and the real deal setup for superior reliability (for a little extra cash), is of course our 36mm hub options with axles listed here: http://www.karcepts.com/shop/product.php?id_product=53

OEM 36mm axles are crazy tough. We keep hearing feedback from customers really pushing them with K-swaps making power in the 500-1000hp mark using our 36mm hubs with OEM axles and still haven't broken one. When you are at that power level, you do have to assume axles are a wear item, but we've been surprised to hear that feedback.

If you have a little k20 w/ 200ish hp, then RSX Base w/ inners swapped will serve you fine.
